JOHN MCE. AMES, OF DONGAN HILLS, NEW YORK.

UNDERFRAME FOR TANK-CARS.

To all whom it may concern.'

Be it known that I, JOHN MCE. Anns, residing at Dongan Hills, StatenIsland, New York, and being a citizen of the United States, haveinvented certain new and useful Improvements in Underframes for Tank-Oars, of which the following is a full, clear, and exact description,such as will enable others skilled in the art to which it apper` tainsto make and to use the same, reference being had to the accompanyingdrawings, which illustrate the preferred form of the invention, thoughit is to be understood that the invention is not limited to the exactdetails of construction shown and described, as it is obvious thatvarious modifications thereof will occur to persons skilled in the art.

1n said drawings: Figure 1 is a composite view showing a centrallongitudinal sectional view of a tank car provided with my invention, atthe left and at the right a side elevational view of the car withfragments ofthe body and underframe broken away; Fig. 2 is an endelevational view of the underframe with a fragment of the tank mountedthereon; Fig. 3 is a transverse sectional view taken on line 3 8 of Fig.1; Fig. 4 is a plan view of the end portion of an underframe includingmy invention; and Fig. 5 is a plan view of a slightly modified formthereof.

The ohject of the invention is to provide an underframe in which the endportion thereof including the end sills, holsters, short side sillsconnecting the holsters and end sills, and diagonal braces running fromthe holsters to the end sills shall he all of one integral casting whichis adapted to he connected with suitable commercially shaped centersills, which center sills extend preferably from end sill to end sill.

Referring to the parts, A A indicate center sills which in the presentconstruction are formed of commercially rolled channels with theirflanges disposed outwardly and extending as shown herein from end sill'to end sill, though it is understood that any other arrangement of thecenter sills and any other shapes may he substituted therefor withoutdeparting from the spirit of the present invention.

B indicates a tank which is mounted on the combined body bolster andtank cradles.

Specification of Letters Patent.

Application led August 6, 1908.

Serial No. 447,201.

C is a casting which is secured to the underside of the tank in suchposition and of such size as to extend downwardly between the centersills A.

D D are stop castings which are riveted to the center sills and areprovided with depending flanges D which are adapted to contact withcorresponding downwardly projecting flanges formed integral with thestop casting C before referred to.

The usual outlet valve E is provided for egress of fluids from theinterior of the tank.

Referring particularly to the end portion of the underframe, 1 is theend sill, 2 2 are the short side sills and 3 3 are the diagonal braceswhich extend from the end sills to the holsters 4.

The end sill is preferably of channel shape in cross section with thebottom flange 5, vertical web portions 6, and top flange 7 which topflange is wider than the bottom flange and extends transversely of theunderframe, as shown in Figs. 4 5 so as to connect with the top flanges7L of the relatively I-shaped side sills 2 thereby forming a cover platewhich is adapted to serve as an end platform.

Formed integrally with the web portion G of the end sill are push-polepockets 8, while hearings 9 are also provided integral with the endcasting, in which hearings 9 are carried the transversely extendingrodsnot shown-for operating an uncoupling device 10, best shown in Figs.1 and 4.

Projecting upwardly from the plate 7 are lugs 11 with which areconnected the vertical straps 12 of the end ladders which lead from theplatforms or plate 7 to the running boards 13 which extend along theside of the tank above the middle line thereof, as best shown in Fig. 1.

Cast integral with the end sills are buffers 14 which are provided withradiating strengthening lianges 15.

The diagonal braces 3, shown in Fig. 4, extend from the middle portionof the end sill to the outer end portions of the holsters and areprovided at their outer ends with vertical flanges 17 with which saidcenter sills are connected, while the rear end portions of said diagonalbraces are connected with the webs of the side sills and with the websof said bolsters. rIhis arrangement is slightly modified in Fig. 5,wherein the diagonal braces 3a extend forwardly from the middle portionsof the bolsters to just back of the push-pole pockets 8, therebyreinforcing the end sill at said push-pole pockets.

Referring to the bolster, it is to be observed that the bolster of thisconstruction is preferably an integral casting comprising the webportions 1S, center filler portion 19, side bearings 20, and jackingplates 21. Surrounding the web portions 18 is a multiform perimetricalflange 22 with intermediate connecting flanges 23 and 24, there being anopening provided in the body portion of the bolster between said flanges23 and 24 for the passage of the center sills A, which center sills areriveted to the vertical flanges 24 which form in effect strut membersuniting the upper and lower portions of said perimetric flanges 22,while the offset flanges 23 serve the same function in strengthening thebolster.

At each side of the middle portion of the bolster there is provided aflanged opening 25 to which leads from above a frustoconical shapedopening 26 adapted to receive the tank bands 27 and as this underframeis intended to be used with tanks of different diameters it is desirablethat the openings 26 shall be wider at the top than at the bottom toaccommodate the tank bands used to anchor tanks of different diametersupon the underframe.

For a better understanding of the function of the conical openings 26, Ihave shown in full and dotted lines in Fig. 3, two tanks of differentdiameter with tank bands entering the openings 26. These tank bandsproject through the openings 26 and into the transversely extendingopenings 25 wherein washers 2S and nuts 29, or any equivalent lockingmeans, are provided upon the ends of the tank bands to anchor them inposition.

It is to be observed that the upper portion of the flange 30 surroundingthe openings 25 is slightly convex to afford a better seat for the saidwashers.

'Referring to Figs. 4 and 5, it is to be noted that there are flanges 32extending longitudinally of the intermediate portions of the top of thebolster which with transversely extending` flanges 33 serve to formsockets for the tank supporting timbers 34, shown in Fig. 3, there beinglongitudinal extensions of the flanges or ribs 32 between the inner endportions of said timber sockets and the part of the bolster which liesoutside of tlre center sills, and there being an intermediate pair ofribs 2a between the ribs 82 thereat.

The under side of the bolster is provided' with flanges 22aL whichextend from the side sill bottom flanges across the lower face of saidbolster, while down-turned flanges 36 between the side bearings 2O areintegral with. the flanges 22a.

It is to be noted that the bottom portion of the bolster between thedown -turned flanges 3G is wider than at the ends and between theseflanges 3G there is provided an integral cast center bearing member 37be` low the center filler 19 which cooperates with said center filler 19and its radiating and transverse ribs to strengthen the central part ofthe bolster.

The jacking plate for casting 21 is provided with a plurality ofobliquely disposed ribs 2.1El and has a rearward extension 2lb, as bestshown in Figs. 4 and 5, said rearward extension projecting beyond thebolsters 4.

Between the flanges 23 and 24 are exaggerated openings 25a in thebolster', through which pass the center sills A. These openings 23"l areabout 12 inches wide and about 15 inches high in the bolsters alreadymanufactured and are adapted to permit the passage of 15 inch centersills through the bolster after the draft lugs, not shown, are securedto said center sills and also provide a sufficient space for theinsertion of riveting tools after the center sills are placed inposition whereby power actuated tools may be used to rivet the centersills to the sill flanges 24 of the bolster. To accomplish this it isnecessary that the opening 23a be wider than the center sills passingtherethrough, as shown in Fig. 3, thereby providing space to permitlateral movement of the center sills in said opening 23a.
